Detailed Description

Referring to fig. 1-8, the tender leaf picking machine of the present invention comprises a profiling picking device, a handle 3, a picking machine shell 2, a leaf collecting box 4 and a fallen leaf rail 7. The picking machine shell 2 and the tender leaf profiling picking device are fixedly connected through a bolt and nut component. The picking machine shell 2 is provided with a handle 3 for operation and a hook-shaped clamping groove 29 for mounting the leaf collecting box 4. The leaf collecting box 4 is provided with a convex clamping strip 30 matched with the hook-shaped clamping groove. The leaf collecting box 4 is connected with the picking machine shell through a clamping strip 30, and is convenient to detach. The fallen leaf rail 7 is fixedly arranged on the picking machine shell 2 by adopting a bolt and nut assembly. Picked young leaves can enter the leaf collecting box 4 through the leaf falling rail 7.

Referring to fig. 1 to 8, the profiling picking device comprises a profiling picking mechanism 1, a left arc-shaped rail 24, a rail connecting plate 26, a right arc-shaped rail 28, an angle controller 8, a base 5, an angle controller swing arm 31 and the like. The angle controller 8 is fixedly arranged on the base 5 by adopting a bolt and nut assembly. The angle controller swing arm 31 is fixedly connected with the profiling picking mechanism 1 through a bolt and nut component. The left arc-shaped track 24 and the right arc-shaped track 28 are fixedly connected to the base 5 through bolt and nut assemblies. The two are fixedly connected with the track connecting plate 26 by adopting bolt and nut components to form the variable-pitch arc track 6. The variable-pitch arc-shaped track is divided into three sections according to different widths, namely a first arc-shaped track 23, a second arc-shaped track 25 and a third arc-shaped track 27. The widths of the first arc-shaped track and the third arc-shaped track are respectively greater than the width of the second arc-shaped track. The profiling picking mechanism 1 can be driven by the angle controller swing arm 31 to closely attach to the variable-pitch arc-shaped track to perform 90-degree reciprocating rotation motion.

Referring to fig. 5 to 7, the profiling picking mechanism 1 comprises a blade 9, an infrared emitter 10, a left rotating plate 11, a left positioning convex plate 12, a left connecting shaft 13, a left torsion spring 14, a left fixing plate 15, a right fixing plate 16, a right torsion spring 17, a right connecting shaft 18, a right positioning convex plate 19, a right rotating plate 20, an infrared receiver 21 and a cutter groove 22. A square mounting hole of the angle controller swing arm 31 is formed between the left fixing plate 15 and the right fixing plate 16. The angle controller swing arm 31 is fixedly connected with the left fixing plate 15 and the right fixing plate 16 through bolt and nut assemblies. The left fixing plate 15 and the right fixing plate 16 are respectively connected with the left rotating plate 11 and the right rotating plate 20 through a left connecting shaft 13 and a right connecting shaft 18, and the left torsion spring 14 and the right torsion spring 17 are respectively installed in the middle positions of the left connecting shaft 13 and the right connecting shaft 18, so that the left rotating plate 11 and the right rotating plate 20 are in preset positions under the condition of no external force. The cutting edge 9 and the infrared emitter 10 are fixedly arranged on the left rotating plate 11 through bolt and nut assemblies. The infrared receiver 21 and the knife slot 22 are fixedly mounted on the right rotating plate 20 through a bolt and nut assembly. The left positioning convex plate 12 and the right positioning convex plate 19 are respectively fixed on the left rotating plate 11 and the right rotating plate 20 by welding.

As shown in fig. 1-8, when in the non-operating state, the infrared emitter 10 emits an infrared signal and is received by the infrared receiver 21, and the angle controller 8 is in the non-operating state, the profiling picking mechanism is in the first arc-shaped track 23, and the blade 9 and the cutter groove 22 are in the separated state.

During operation, the tender leaf picking machine is held by hand to move, so that tender leaves are located between the blade 9 and the cutter groove 22, due to shielding of the tender leaves, infrared signals sent by the infrared transmitter 10 are not received by the infrared receiver 21, at the moment, the angle controller 8 starts to work in one period, and the angle controller swing arm 31 drives the profiling picking mechanism 1 to rotate in the arc-shaped track.

When the profiling picking mechanism transits from the first arc-shaped track 23 to the second arc-shaped track 25, as the width of the arc-shaped track is narrowed, the left and right arc- shaped tracks 24 and 28 respectively extrude the left and right positioning convex plates 12 and 19, under the action, the left and right rotating plates 11 and 20 respectively rotate around the left and right connecting shafts 13 and 18, the knife edge 9 and the knife groove 22 move in the same direction until the direction picking mechanism moves to the second arc-shaped track 25, at the moment, the knife edge of the knife edge 9 is contacted with the groove bottom of the knife groove 22, in the process, the tender leaves are separated from the tea stems under the action of lifting and shearing, and the tender leaf picking machine finishes the picking process of the tender leaves.

Under the action of the angle controller 8, the copying picking mechanism 1 continues to move along the second arc-shaped track 25, when the copying picking mechanism transits from the second arc-shaped track 25 to the third arc-shaped track 27, the track width is widened, under the action of the left and right torsion springs 14 and 17, the blade 9 and the cutter groove 22 move back to the back until the copying picking mechanism is completely separated, and picked tender leaves fall onto the leaf falling track 7 and finally fall into the leaf collecting box 4. When the profiling picking mechanism rotates 90 degrees, the angle controller 8 controls the profiling picking mechanism 1 to rotate reversely, when the profiling picking mechanism 1 runs to the first arc-shaped track 23 again, the blade 9 and the cutter groove 22 are in a separated state under the action of the torsion springs 14 and 17, and when the angle controller 8 controls the profiling picking mechanism 1 to complete downward rotation movement of 90 degrees, a picking process of tender leaves is completed.

The above embodiments are further illustrative of the above aspects of the present invention, but should not be construed as limiting the present invention. All the technologies realized based on the above contents belong to the scope of the present invention.
